Understanding the Difference Between await vs async in JavaS

Are you confused about when to use await and async in JavaScript? Let's dive into the details of these two keywords and understand the differences between them.

What is await in JavaScript?

In JavaScript, the await keyword is used in an async function to pause the execution of a function until a Promise is settled. This allows for asynchronous code to be written in a synchronous manner, making it easier vietnam phone number read and maintain. When using await, you must always be inside an async function.

Example of using await:

async function fetchData() {

const response = await fetch
const data = await response.json();

return data;










In this example, the fetchData function will pause execution at each await statement until the Promise is resolved.

What is async in JavaScript?

The async keyword is used to define an asynchronous function in JavaScript. When a function is declared as async, it automatically returns a Promise. This allows you to use the await keyword inside the function.

Example of using async:

async function fetchData() {

return fetch('https://api.example.com/data')

.then(response => response json.
